common: fs: Rework the Common Filesystem interface to make use of std::filesystem (#6270)
* common: fs: fs_types: Create filesystem types

Contains various filesystem types used by the Common::FS library

* common: fs: fs_util: Add std::string to std::u8string conversion utility

* common: fs: path_util: Add utlity functions for paths

Contains various utility functions for getting or manipulating filesystem paths used by the Common::FS library

* common: fs: file: Rewrite the IOFile implementation

* common: fs: Reimplement Common::FS library using std::filesystem

* common: fs: fs_paths: Add fs_paths to replace common_paths

* common: fs: path_util: Add the rest of the path functions

* common: Remove the previous Common::FS implementation

* general: Remove unused fs includes

* string_util: Remove unused function and include

* vfs_libzip: Migrate to the new Common::FS library

* service: bcat: Migrate to the new Common::FS library

* yuzu: main: Migrate to the new Common::FS library

* vfs_real: Delete the contents of an existing file in CreateFile

Current usages of CreateFile expect to delete the contents of an existing file, retain this behavior for now.

* input_profiles: Don't iterate the input profile dir if it does not exist

Silences an error produced in the log if the directory does not exist.

* game_list_worker: Skip parsing file if the returned VfsFile is nullptr

Prevents crashes in GetLoader when the virtual file is nullptr

* common: fs: Validate paths for path length

* service: filesystem: Open the mod load directory as read only
